FOLDING BOX.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed May 20, 1905. Serial No. 261.429.

To all whom it may concern.-

Be it known that I, HENRY W. STUART, a citizen of the United States,residing at Fernbank, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Folding Boxes, of whichthe following is a specification.

The object of my invention is to provide an improved box of economicaland comparatively rigid construction and which may be folded flat forshipment or storage. My invention consists of a box constructedsubstantially as hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a distended boxembodying my invention Fig. 2, a perspective view of the box partiallyfolded; Fig. 3, a perspective view of the box when further folded, andFig. 4' a perspective View of the box completely folded.

The box is constructed of the four sides A, B, O, and D, bottom E,-andlid F. At one corner sides A and B are left open and side A providedwith a flap a, having a tongue 0/, and side B with a slot 1) fordetachably securing the two sides together. The bottom E is scored orcreased for bending on diagonal lines 6 e and e e. Lid F is permanentlysecured to side D and is provided with sealing flaps or flanges f, whichare scored or creased on linesf for folding.

In folding the box tongue a is removed from slot 5, so as to leave thatcorner free to open in folding, as indicated by dotted lines in Fig. 1.Then by folding the bottom on line e 6 side A is folded against side D,side B against side C, and bottom E diagonally doubled onto itself, asshown in Fig. 2. In making this fold flap a and tongue a are foldedinside of side A, as indicated in dotted lines. As sides A and B thuslie within sides D and C, respectively, when folded it is necessary tomake sides A and B a little shorter than sides D and C to obtain asmooth fold. In constructing the box it will generally be foundpreferable to attach the lid to one of the longer sides D or C forconvenience in folding. The box is next folded on line e e and at thecorner between sides 0 and D to bring sides B and 0 down onto sides Aand D, when the box may be laid out flat and flaps f folded down, asshown in Fig. 3.

It will be observed that the crease e 6, connecting the corners of thebox adjacent to the open corner, is an inwardly-folding crease,

while the crease e a, connecting the open corner with its oppositecorner, is inwardlyfolding in the portion remote from the open cornerand outwardly-folding in the portion adjacent to the open corner.

If desired, the box may be further folded on line a w, as shown in Fig.4:. Tapes G may be secured to sides A and C for fastening the lid whenthe box is filled. By this construction it will be noted that I providea folding box in which the sides are uncreased, and thus retain all oftheir original stiffness and rigidity, in which the bottom may be madeof a single piece of material suitably creased and in which the lid ispermanently attached to the box. a

It is obvious that the box when folded flat may be readily distended andsecured in boxform by engaging tongue at in slot 1).

While I have illustrated and described the preferred construction forcarrying my invention into effect, this is capable of variation withoutdeparting from the spirit of the invention. I therefore do not wish tobe limited to the exact construction shown in the drawings; but

What I claim as new, and desire to secure by Letters Patent, is

1. In a folding box, the combination of four uncreased sides permanentlysecured to the bottom and at three of the corners; a detachableconnection between the sides at the fourth corner; an inwardly-foldingcrease in the bottom, connecting the corners of the box adjacent to theopen corner and a crease in the bottom connecting the other corners,said last-named crease being inwardly-folding in one portion andoutwardly-folding in the other portion, substantially as specified.

2. In a folding box, the combination of four uncreased sides permanentlysecured to v the bottom and at three of the corners; a detachableconnection between the sides at the fourth corner an inwardly-foldingcrease in the bottom, connecting the corners of the box adjacent to theopen corner; and a crease in the bottom connecting the other corners,said last-named crease being inwardly-folding in the portion remote fromthe open corner, and outwardly-folding in the portion adjacent thereto,substantially as specified.

3. In a folding box, the combination of four uncreased sides permanentlysecured to the bottom and at three of the corners; a

tongue-and-slot connection between the sides i open corner, andoutwardly-folding in the at the fourth corner; an inwardly-foldingportion adjacent thereto, substantially as crease in the bottom,connecting the corners specified.

of the box adjacent to the open corner; and H. W. STUART. a crease inthe bottom connecting the other Vitnesses:

corners, said 1ast-named crease being in- J. F. EARLY,

Wardly-fo1ding in the portion remote from the BRAYTON G. RICHARDS.
